Quizplus · Accepted Answer

An operating characteristic curve (OC curve) is a graphical representation of the probability of accepting various levels of defects. It is a useful tool to determine whether a sampling plan is adequate for the quality control process. Options A and B are not correct as they do not refer to a curve that shows the relationship between the probability of accepting a level of defects and the actual level of defects. Option D refers to a chart used for counting the number of defects within a subgroup.
